Patent CA-2435623-A1 (CA)
Inventor: MUKHERJEE SHYAMA
IPC: H01L21/768
Filed: 2002-01-22
Abstract: La présente invention concerne l'aplanissement de surfaces comme cela se présente souvent dans le cas de la fabrication de circuits intégrés, plus particulièrement pour les conducteurs de cuivre et les couches barrières Ta/TaN des interconnexions a damasquinage simple ou double. La présente invention concerne plus particulièrement des procédés d'aplanissement pour les interconnexions Cu/Ta/TaN, en utilisant en l'occurrence une couverture visqueuse ayant tendance à se réfugier dans les dépressions de surface, protégeant ainsi lesdites dépressions contre les phénomènes d'attaque chimio-mécanique. Pour certains modes de réalisation, la couverture visqueuse contient des espèces qui empêchent l'enlèvement du cuivre dans les zones de la surface en contact avec la couverture visqueuse. Ces espèces peuvent être une solution sensiblement saturée d'ions cuivre parmi d'autres additifs, ce qui bloque la dissolution du cuivre d'interconnexion dans la couverture de protection. Selon certains modes de réalisation de la présente invention, la couverture visqueuse peut s'ajouter avant l'introduction des agents d'attaque chimique sur la surface de la plaquette, mais aussi, on peut introduire l'agent d'attaque chimique et la couverture visqueuse sensiblement simultanément, en général pendant la centrifugation d'égalisation de la plaquette.

Abstract: An inflator includes a hollow handgrip and an air cylinder having a shaft. One end of the shaft is connected with a piston in the cylinder and the other end of the shaft is provided with a stud extending out of the cylinder. A bottom wall and an opening are arranged respectively at opposite ends of the handgrip. A tapped hole is formed in the bottom wall for locking the stud. Through the opening, the cylinder may be stored in the handgrip to lessen the volume of the inflator. When using the inflator, a user draws the cylinder out of the handgrip and lock the stud to the tapped hole through the bottom end of the handgrip to thereby extend the shaft. Air is pumped out through an outlet of the cylinder by reciprocal axial motion of the shaft.

Title: Multiple split optical waveguide
Inventor: TAKAHASHI FUMIO
IPC: G02B6/125
Filed: 2002-04-12
Abstract: Disclosed is a multiple split optical waveguide in which a branch waveguide path at an output end of a branch part of a first stage defines an acute angle with respect to an input waveguide path, and a branch waveguide path at an input end of a branch part of an n-th stage is no more inclined toward a central axial line defined by an extension line of the input waveguide path than a branch waveguide path at an input end of a branch part of an (n+1)-th stage, n being an integer equal to or greater than two. Thus, the waveguide paths are prevented from spreading beyond the first branch angle, and it becomes easier to bring the outer waveguide guide paths back toward the center. This prevents an increase in the variations in length between the outer and inner waveguide paths.

Title: Optical spectral power monitors employing time-division-multiplexing detection schemes
Inventor: GARRETT MARK H
IPC: G02B6/42
Filed: 2002-12-09
Abstract: A method and apparatus for optical spectral power monitoring using a time-division-multiplexed detection scheme. The apparatus uses a wavelength-dispersing means (120) such as a diffraction grating to separate an optical signal into multiple spectral channels, and an array of beam-manipulating elements (140) positioned to correspond with the spectral channels. The beam-manipulating elements are individually controllable so as to direct the spectral channels into an optical detector (150) in a time-division-multiplexed sequence. The apparatus may further employ a polarization diversity scheme for polarization-insensitive operation. This enhances the spectral resolution of the apparatus while providing improved accuracy in spectral power detection. Spectral power monitors constructed according to the present disclosure are well-suited for WDM optical networking applications.
